Picking up the above, after the spoon fell unconscious, the chopsticks have been by his side.

There is a layer of rock more than five meters thick between the upper and middle layers, and no matter how the drone bombs, even if the ammunition is consumed, it will not blow up, not to mention that someone will emerge from a small hole from time to time to shoot down the drone.

As people fought back, it was discovered that the flames would burn off the gas mist, and gradually, people began to take the initiative, and the number of drones was constantly decreasing.

In this way, it took less than an hour to kill all the drones roaming in the upper layer.

The drones above outside were still waiting and did not rush in, and people took advantage of this opportunity to quickly block the vent.

Chopsticks collect the wreckage of the drone, take it all apart, and then use these useful parts to reassemble into a new drone. He secretly found a place where no one was and released the drone he had made.

The drones that flew into the sky were seen by those in the distance, and several drones were separated and began to chase the chopsticks.

Chopsticks' drone attack is not good, but it flies fast, with two thrusters, much faster than those with only one. After a while, the drone of the chopsticks disappeared into the observation range of the drone that was chasing after it.

These stopped drones were just about to prepare for the return trip, when several tracking missiles suddenly flew out on the ground, and all the drones in the sky were shot down with a few clicks.

Dozens of people came out of the ground, cheering, celebrating the small victory.

The drones on standby in the distance sensed what was happening here, turned their heads one after another, and then flew over with a whoosh, and at the same time opened fire, and dozens of missiles and various poison gas bombs and explosive bombs fell to the ground one after another, and for a while, the ground shook with a bang.

And the people here are not idle, they have fired at the drones in the air, some people use machine guns, dada da shoot down one drone after another, some people carry bazookas on their shoulders, swishing to hit one drone after another, some people carry flamethrowers on their backs, burning the poisonous gas mist that falls on the ground, some people stand behind automatic cannons, clattering one drone after another, and some people lie at the back, using sniper rifles to penetrate the fragile body of the drone.

There are a lot of drones, and the human firepower is very fierce, and after a while, there are a lot of casualties on the human side, and there are still a lot of drones flying around in the air, and it is difficult to hit the fast-moving drones with only human eyes to aim. For a time, the human side fell into passivity.

Fast! Fall back!

Someone shouted.

The machine gunner was responsible for breaking the rear, covering the rest of the retreat underground.

The drones did not miss this good opportunity and increased their firepower one after another, throwing all the remaining ammunition down.

In a short time, there were many human corpses lying on the ground, and all those who survived were withdrawn to the ground.

Humanity failed miserably.

There are still a dozen drones in the air, and there are less than ten humans who have withdrawn underground.

Everyone lowered their heads and did not speak, and the atmosphere was sad.

Some were sobbing quietly, some were silently wiping their sniper rifles, some were rolling cigarettes, and some were leaning against the wall with their eyes closed.

Unfortunately, the chopsticks did not retreat to the ground in time and were trapped in the tree, and it was not possible to climb up, and if they climbed down, they would be discovered, so they could only hide quietly in the tree.

The drone in the sky flew back and forth in the air a few times and left.

Chopsticks quietly climbed down from the tree, looked around, and after making sure that there were no drones again, they ran to the entrance and exit that retreated to the underground, called everyone out, and moved the bodies of the dead brothers and sisters underground.

The robotic ground force finally came to the human base after the drone waited.

The ground forces of robots, as far as humans know so far, have roughly three major types of troops, they are:

Simple Geometry Classes: Spherical Classes, Cubes, Tetrahedral Classes;

Five Elements: Gold Class, Main Defense, Wood Class, Main Repair, Water Class, Main Control, Fire Class, Main Attack, Earth Class, Main Scout;

Animal Arms: Elephant, Lion, Tiger, Cheetah, Wolf, Dog, Swift Cat, Gopher.

These are just a few of the ground forces of robots, not to mention the air forces, sea forces and space forces.

At this moment, what came here was a lion-shaped machine, six wolf-shaped machines, and thirty rat-shaped machines, and the three arms stood neatly and neatly in front of and back, very organized and disciplined.

The people hiding underground saw the lion-shaped mechanical body with a shiny metallic luster, the mighty body, which was completely a perfect work of art, and the wolf-shaped mechanical body behind him, with its slender body containing huge explosive power, and then some cute mouse-shaped mechanical bodies behind it, with round ears and slender tails, if it weren't for the size of a coconut, people would really be deceived by the cute appearance of the mouse-shaped mechanical body.

At the command of the lion-shaped machine, all the rat-shaped machines scattered in all directions, and they went to find the hole to enter the ground.

When the people underground saw it, they all took action and went to guard the entrance and exit.

One of the gophers' skills is to make holes, and nothing can stop them from going underground. In a few moments, a few lucky gophers arrived on the upper level of the human base, and the people guarding there opened fire on the rat-like mechs as soon as they spotted them.

The defense of the rat-like machine body is very high, and the bullets of the human machine gun cannot penetrate it at all, and at most it only affects the speed and direction of the rat-like machine.

Crackling, people used a lot of bullets, not even a single rat-shaped mechanical body was left, and they were allowed to wander around here and drill back the way they came.

The rest of the rat-like mechs continued to go deeper, and several had already made it to the middle and lower levels of the base.

In a hurry, the panicked people tried to attack the rat-like mechs with missiles and sniper rifles, with little success, but not in vain.

A rat-like mechanical body was shot through the head by a sniper rifle bullet and fell to the ground, its body still twitching.

The scientists in the base who knew how to mechanics sat around and were silent as they looked at the rat-shaped mechanical body on the table whose head had been shattered.

How far has the technology of robotics progressed?

An old man breaks the dullness.

The internal structure of the rat-shaped mechanical body is very complex, and there are countless tiny parts, including more than 100 nano-sized ones, which are not at all possible with the current level of human science and technology.

Well, it seems that robots have begun to evolve autonomously, and their learning ability is also growing rapidly, and now our technology is no longer on the same level as robots, and if robots are allowed to develop, it is only a matter of time before humans become extinct.

Another scientist sighed.

Hugh wants to raise the morale of the enemy and destroy his own prestige, robots are robots after all, it is an emotionless iron lump!

An old scientist slapped the table hard and yelled.

It was also an iron lump with high intelligence.

The scientist retorted in a low voice.

At a time when people are talking negatively about the fate of mankind, chopsticks have roughly figured out how drones work. He began to try to hack into the drone's command system, but the drone's firewall was very strong and difficult to get over for a while.

The robots on the ground, nay, the mech, already have a rough idea of the general structure of the underground human base, so they ask the headquarters to launch a ground-penetrating bomb, and by the way, change the nuclear bomb on the head of the ground-penetrating bomb into a poisonous swarm.

At this time, in a corner of the headquarters of Nuoda, a nuclear bomb launch platform slowly rose, the protective cover of the launch port opened to both sides, and boom, a thick and long intercontinental missile slowly rose into the sky, and then turned a corner in the sky and flew towards the deep mountains and old forests.

At this time, the chopsticks did not know that the robot had launched an intercontinental missile, and it would not take a few minutes to come.
